The Horse Drawn Mower Book
When touring Tony and Fran McQuail’s horsepowered farm outside of Lucknow, Ontario, we noticed something strikingly different about their horsedrawn mower. Every other knife section was upside-down! Following the example of their Amish neighbors, Tony had converted the sicklebar mower to the SCH EasyCut system manufactured by S.I. Distributing. He explained that the alternating face-up/face-down sections balanced pressure on the knife, preventing it from bending or breaking. More importantly, the heavy duty enclosed guards maintain the critical scissor-like action for smooth, carefree mowing without the need for constant adjustment.
If you are in a position to choose which make and model of mower you might wish to work on might I put in my vote for either the McD/Internationals #7 & #9 or the John Deere Big Four. These were the last and most plentiful models made and some parts are still available with a fair measure of aftermarket cutter bar parts which are interchangeable.
